I was a student at the University of MO, College of Agriculture from 71-75. It was during that time period the "tree hugger" movement started.

They didn't want chickens raised in cages, hog confinement operations, or the use of commercial fertilizer or pesiticides. My Ag econ professor had the perfect solution for them to allow us to turn back the clock 100 years. All they (the tree huggers) had to do was: Determine which 1/2 of the world's population (at that time) would be allowed to starve to death.

Sorry guys, but nothing that commercial agriculture does keeps me from eating food from the grocery store.
